Multipath Ring Routing in Wireless Sensor Networks

Gui Min Huang, Wu Jin Tao, Ping Shan Liu, Si Yun Liu
2013 Applied Mechanics and Materials  
However, these routing protocols pay little attention to the transmission reliability. Therefore, this paper proposes a new multipath ring routing algorithm for WSNs.  ...  The proposed algorithm utilizes ring level to separate sensor nodes into several sections, which can improve the reliability of the data transmission.  ...  Therefore, redesigning a robust routing algorithm to ensure correctness of data transmission is vital to the WSNs.  ...
